Digital color x-rays are based on the same advanced technology that is used when nuclear physicists look for new elementary particles. The great scientific challenge in constructing a color x-ray camera is to be able to shrink the large-scale detection equipment used by nuclear physicists to the microscopic format.
The readout electronics for each pixel in the camera's picture sensor must be squeezed into an area of 55 x 55 µm, and what's more be x-ray safe. The Mid Sweden University researchers have solved these design problems. Furthermore, they have shown that Medipix2 can be used to reduce the radiation dosage in dental x-rays. Industry also expects to be able to use the technology to see the consistency of materials using x-rays.
"With our digital color x-rays it will be possible to cut the radiation risk in half for x-ray examinations," says Börje Norlin.
Using advanced computer simulations of the next generation of x-ray cameras, Mid Sweden University has also developed ways to enhance the quality of color x-rays.
These cameras will have higher resolution and be able to show more colors of higher quality.
In connection with these dissertations, CERN will be holding one of its quarterly meetings in Sundsvall, Sweden, to discuss the further development of color x-ray technology.
The dissertations are:
Xavier Llopart, Design and Characterization of 64K-Pixel Chips Working in Single Photon Processing Mode (Xavier Llopart is stationed at CERN in Geneva.)
Jan Lundgren, Simulating Behavioral Level On-Chip Noise Coupling
Börje Norlin, Characterization and Application of Photon Counting X-ray Detector Systems

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
